The Many Lives of Nick Buoniconti, an HBO documentary debuting at 10 p.m. Tuesday, offers an absorbing glimpse into a remarkable life packed with enormous professional success but devastating personal loss.

It was appropriate that HBO produced this special, considering Buoniconti opined for 23 years as a commentator on the network’s Inside The NFL. And HBO neatly fits a life with so many layers into a documentary that’s thoroughly worth your time.

There is crisp chronicling of all the successes — his vital role as a defensive stalwart on the great Dolphins teams of the early 1970s and a glorious career culminating in his 2001 induction into the Pro Football Hall of Fame. And later, a post-NFL life as a practicing attorney, an agent, a broadcaster and president of US Tobacco Company during the late 1970s and early 1980s.

But there’s also the dispiriting, but necessary, detailing of the tragic paralysis of son Marc and the CTE symptoms that have made Nick Buoniconti, in his words, “half the man I used to be.”
